At least one; side of each panel may be cut away or offset at both top and bottom.

Forms for concrete may be made of assembled panels 20 made up of face plates 2| which may be of square or rectangular or any other suitable form. They are shown as square. The panel face plates are preferably cut out at at lea-st one edge at top and bottom as shown at 22 for a purpose to be explained. Preferably, the face plates are backed and reinforced by angle bars 23 which may extend about their entire peripheries and also at suitable intermediate points, if desired. The peripheral angle bars are bent and formed as at 24 to hollow the contour of the out out portions 22. Perforations 25 are provided in the upstanding Wings of the peripheral angle irons. A perforation is in the bent portion 24 and they are distributed. preferably at regular intervals throughout so that when adjacent panels are brought into side by side contact the perforations may register and be used for positioning and fastening together panels. As shown in Fig. 1, a smooth or uncut edge of one panel may be brought into contact with a cut edge of an adjacent panel so that the portions 24 may form seats or sockets for connecting rods 26 in the ends of which are perforations 21 so positioned that when they are brought into register with the perforations in the panels they may position the panels the proper distance apart to form a wall of the desired thickness when concrete is poured into the form. In Fig. 1 the tops of adjacent panels are shown as level but obviously they need not be. A top hole in the side of one panel may be put in register with a lower hole on an adjacent panel. The panels and connecting rods may be held in proper relative position by any suitable means, such as pins, passing through the holes. Such a pin 28 is shown as mounted on a rod or bar 29 acting as a handle and carrying a clamp 30 which may enclose and hold together peripheral angle bars 23 of adjacent panels 20. The outer edge of the clamp 30 may be slightly tapered or turned out, as at 3|, as indicated in Fig. 2, so as to facilitate installation on the angle bars 23.

Various forms of tie rods may be used. As shown in Fig. 3, portions may be cut out on one or both sides as at 32 to weaken the rod so that after the panels are removed from the cast wall, the tie rods may be broken off within the wall so as to leave cleared surfaces. As indicated in Figs. 3 and 4, the portions 33 cut out at 32 may be retained and turned in the same or opposite directions so as to engage and seat firmly in the poured concrete. 7 This may facilitate the breaking off of the protruding ends by forming a sturdy seat for the body of the tie to resist the breaking action when the protrudin ends are struck the breaking blow. A blow of a hammer on the protruding ends of the tie bars may break them off. When desired, a tapering tie rod 34 may be employed, having a slot 35 at its larger protruding end. About the slotted end may be placed a washer 36 resting against the angle bars 23 of the panels (see Fig. 8). After the concrete is cast, a wedge 31 may be driven into the slot 35 and exert pressure against the washer or buffer 36 and loosen the rod 34 so that it may be withdrawn and used again if desired.

In order to position properly the panels of the forms on the base or footing 41 for the wall, there may be provided an aligner 38 provided with holes 39 on one or both ends through which may be driven a spike 40 into the base 41 to hold it in the desired position. The aligner may be provided with upwardly extending pins 42 to engage perforation-s 25 in the bottoms of panels 26 to hold them in proper position for the desired wall thickness. The pins 32 shown in Figs. 14 and 15 may be placed the proper distance apart to engage end holes 25 in the bottoms of adjacent panels 20 so as to bring the edges of their faces and angle bars 23 into close contact to receive the clamp 30 and present an unbroken face to the concrete to be poured. Instead of using pins on the aligner there may be provided a strip 43 with struck up portions 34 suitably spaced to engage and grasp the sides of the angle bars 23 so as to hold the panels in proper desired position. When the ends of adjacent panels are inserted between the same pair of portions 44 (e. g. the two at the left of Fig. 13), the panels will be positioned to present a smooth surface to the poured concrete. If it is not desired to employ perforations to position the aligner, there may be used to seat 45 provided with a perforation 46 for a dowel or spike to fix it to the base. Clips t! struck up from 45 may be provided and after the strip is adjusted transversely to 45 to the proper position, the clips 41 may be hammered down to clasp and rigidly hold the strip. The aligners are shown adapted to position four rows of panels, but they may have some of the pins 42 or struck up portions 44 omitted or be used for only two rows of panels.

For a solid wall two rows of panels, as indicated in Fig. 1, may be suflicient. An arrangement for a hollow wall or a partially hollow wall is indicated in Fig. 8. Outer rows 48, 49 of panels.

may be associated with inner rows 5U, 51. The face plates 2| of row 50 may face those of row 48 and those of row 49 face those of row 5|, thus leaving space between the backs of the rows 50 and 5| free of concrete and leaving hollows in the wall for pipes, cables, etc. At the ends of the rows 58 and 5| may be provided solid blocking strips 52 to prevent concrete from entering between the rows 50 and 5|. The strips 52 may have edges perforated to cooperate with the perforations of the peripheral angle bars of the panels of rows 50 and 5! for holding them in position, or may have a plate attached at right angle to top with perforations registering with two of pins 51 in tie 54. Where the wall turns there may be provided angle panels 29a formed at the desired angle of the wall turn. At the outer, side of the wall turn these special panels 20a may not be needed but angle bars 53 may be used having both wings perforated to register and cooperate with the adjacent panels for positioning and holding in position.

In this hollow wall arrangement the aligner strips may be employedprovided as shown in Figs. 12 to 15 with mechanism for receiving the fourg courses of panels and: are. used only with At its center, the bar t may be provided with an overlying plate carrying depending pins or with perforations for inserting pins .51 to engage the holes in the panels of the inner rows 50 and 5!. Lugs orarms 58 extend laterally from the bar 54. After the concrete is cast, the bar 54 may be knocked upwardly. It will leave in the concrete a recess, being an impression of it and its lugs 58. The inner rows of panels or units 5.0;;and 5| are then removed. A correspondingly formed but shorter tie bar 59 has at its ends lugs vor arms. 60 positioned to enter the recesses formed by the arms 58. The bar 59 also carries a plate 6| but provided with upwardly extending pins 52 so as to engage panels 55a and 5m and hold them directly above the position occu-- pied by the panels of the inner rows 50 and 5! previously removed. Thus, when the wall is carried to a greater height, as shown in Fig. 17, the bars 59 will insure the sides of the hollow in the wall being straight and smooth up and down. The bars 59 will be covered with concrete and may be left in the walls and, since their area is relatively small, they may not unduly block or impede the hollow space in the finished wall, while at the same time permanently tying the two walls together as a single unit.

In Fig. 2 is'shown a hole 10 in the rod or bar 29. When the clamp 30 is in the position shown in Fig. 1 the hole 29 will be in register with holes 25 so that a nail or the like may be passed through the holes to lock or hold the clamp in place.

The specific sizes, shapes and details of the structures illustrated may be varied within wide limits since they form no part of the invention which may be embodied in other structures.
